Wood sorrel pesto is the perfect way to bring a wild, fresh touch to your meals. It has a bright lemony flavor from the fresh wood sorrel leaves, balanced by the creamy earthiness of hazelnuts and the salty umami in fresh grated parmesan.
In a food processor (or using a mortar and pestle), process the hazelnuts and salt until finely ground. Add the garlic and process until the mixture is uniform.
Add the wood sorrel, about ½ cup at a time, processing until finely ground.
With the processor running, slowly drizzle in the olive oil until the pesto reaches your desired consistency.
Stir in the lemon zest and grated Parmesan. Season with salt to taste, if needed.
Store in an airtight container in the refrigerator until ready to use. It’ll keep about 1 week in the fridge, or up to 6 months in the freezer.
Notes
Traditional pesto recipes often use pine nuts, but we’ve swapped them out for either hazelnuts or Marcona almonds in this recipe.Hazelnuts add a slightly sweeter, more earthy flavor, which beautifully complements the tartness of the wood sorrel. They also bring a bit more texture to the pesto, offering a satisfying crunch that pairs perfectly with the smoothness of the olive oil and the creaminess of the Parmesan.Marcona almonds are a bit more expensive, but they have a more neutral flavor, without the earthy/woodsy flavor you get from hazelnuts.I've used both with great results.Honestly, feel free to use whatever nuts you have on hand. Pine nuts work wonderfully for a neutral flavor, though they're often a bit pricey. Good substitutes are sunflower seeds, pumpkin seeds, and cashews. All add a wonderful creaminess and body to the finished pesto, though hazelnuts do work exceptionally well with wood sorrel in particular.
